SPECIFICATION forming part of Letters Patent No. 651,030, dated June 5, 1900.

Application filed April 5, 1899. RenewedMay 1, 1900. Serial No. 15,131. (No model.)

To all whom it may concern:

Be it known that 1, JOHN T. FLIPPEN, Sr.,

a citizen of the United States, residing at Tre- I low, in the county of Pittsylvania and State of Virginia, have invented a new and useful Fumigator, of which the following is a specification.

The invention relates to improvements in fumigators.

The object of the present invention is to improve the construction of fumigators and to provide a simple, inexpensive, and efficient apparatus adapted for discharging the fumes of various chemicals and designed to be employed for impregnating various articles of food with a preservative compound and for spraying plants with poison for destroying various forms of insect life.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a fumigator constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a horizontal sectional view.

Like numerals of referencedesignate corresponding parts in all the figures of the drawings.

1 designates a casing constructed of suitable material and preferably rectangular in section, as illustrated in Figs. 2 and 3 of the accompanying drawings, and it is provided near its bottom with a horizontal partition 2, dividing the easing into upper and lower compartments. The horizontal partition is provided with openings 3 for the passage of the fumes given off by chemicals contained Within a receptacle 4, located in the upper compartment and adapted to be introduced into and removed from the same by means of a door 5, which may be of any desired construction. The receptacle, which may be of any preferred construction, is supported in an opening of the horizontal partition, which forms a seat 6 for the receptacle.

lVithin the casing is arranged .a pump '7, adapted to draw the fumes from the upper casing and discharge them through a tubeor Lil pipe and consisting of a vertical pump wellor casing 9 and a plunger 10, operating through a perforation of the top of the casing 1. The

plunger consists of a rod provided at its upper end with a suitable knob or grip 1.1 and having a head 12 at its lower end fitting snugly within and conforming to the configuration of the pump Well or casing. The

pump well or casing, which extends from the horizontal partition to the top of the main casing 1, is preferably rectangular in crosssection, and when the plunger of the pump is moved upward the fumes are drawn from the upper compartment through the openings of the horizontal partition into the pump well or casing, and they are dispelled through the discharge-tube S by the down ward movement of the plunger.

An inwardly or upwardly opening valve 13 is arranged at the lower end of the pump well or casing, and an outwardly-opening valve 14 is mounted within a cap 15, to which the discharge pipe or tube is secured. The cap 15, which is arranged on the exterior of the main casing l, is disposed over an open ing thereof, and it receives the inner end of the discharge pipe or tube. The top of the main casing is provided with a handle 16 to enable the device to be readily carried.

The invention has the following advantages: The fumigator, which is simple and comparatively inexpensive in construction, is strong and durable and adapted to be readily operated. It is capable of being used for 8 5 a variety of purposes and is adapted to discharge the fumes of preservative'compounds on food substances, and it forms a convenient means for spraying plants and the like with poisoning substances for destroying all forms of insect life. The chemicals or compounds are conveniently arranged within the removable receptable, and the fumes are drawn through the perforations or openings of the horizontal partition into the pump well or casing on the upstroke of the plunger and are expelled through the discharge pipe or tube on the downstroke' of the pump. The lower valve opens automatically to permit the fumes to enter the pump and the outer loo valve operates similarly to permit the fumes to be discharged. While the fumes are being drawn into the pump the outer valve remains closed to prevent the fumes from being diluted with air before being discharged.

Changesin the form, proportion, size, and the minor details of construction within the scope of the appended claims may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

What is claimed is- 1. A device of the class described comprising a main casing, a horizontal partition arranged within the main casing and provided with perforations and dividing the said main easing into upper and lower compartments, the upper compartment being designed to receive a chemical or a compound, a pump mounted within the casing and extending upward from the horizontal partition and communicatin g with thelower compartment, said pump being adapted to draw the fumes from the upper compartment through the perforations of the partition into the lower compartment, and a discharge pipe or conduit connected with the pump, substantially as described.

2. A device of the class described comprising a casing having a door, a partition located below the door and dividing the casing into upper and lower compartments, said partition being provided with openings for the passage of the fumes, a receptacle adapted to be supported by the partition, a pump mounted within the upper compartment of the casing and communicating with the lower compartment, and a discharge pipe or conduit connected with the pump, substantially as described.

3. A device of the class described comprising a main casing, a horizontal partition having openings and arranged within the main casing, said partition dividing the main casing into upper and lower compartments, a pumpcasing arranged within the upper compartment and extending from the partition to the top of the main casing, a plunger operating in the pump-casing, a cap mounted on the exterior of the main casing and communicating with the pump-casing, and a discharge pipe or tube connected with thecap, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
